What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundStroke is commonly accompanied by motor disorders secondary to the initial injury, and at the mitochondrial level, there is an increase in oxidative stress, causing tissue damage and relating to alteration in motor function. Functional electrical stimulation (FES) therapies can be useful in stroke patients aimed at restoring motor function and improving life quality. Several studies have recently proposed that electrical stimulation modulates mitochondrial biogenesis and physiology; however, the effect of FES on individual complexes comprising the mitochondrial electron transport chain (mETC) remains unknown.
methodsTo study the effect of FES therapy on the activity of the mETC, in vitro analyses were conducted using UV-spectrophotometry of the activity of the complexes (I, II, and IV), glycerol-3-phosphate dehydrogenase (G3PDH), and monoamine oxidase (MAO) in peripheral blood mononuclear cells (PBMCs) obtained from stroke patients. Patients' activity of complex II and MAO was also determined in platelets. Analyses were measured before and after 12 rehabilitation sessions based on FES therapy combined with physical exercises.
resultsThe results showed that the activity of the mETC, G3PDH, and MAO was significantly reduced in pre-intervention stroke patients compared to healthy volunteers, both in PBMCs and platelets, except for complex II in platelets and MAO in PBMCs. Interestingly, FES intervention increased the mETC, G3PDH, and MAO activity in both cell types of stroke patients.
conclusionsThis preliminary study indicates that intervention can restore motor function and mitochondrial activity, which are damaged in stroke patients. However, more research is needed to determine if changes in mitochondrial activity can be used as biomarkers of the pathology and/or the efficacy of intervention.
